✓ Apply robust input validation and secure business logic practices
✓ Protect sensitive data and secrets at rest and in transit
✓ Build, test, and deploy applications securely
✓ Apply role-based and claims-based authorization to protect APIs and web applications from unauthorized access.
✓ Use data annotations, custom validators, and sanitization to prevent SQL injection, XSS, and insecure deserialization attacks.
✓ Encrypt data using .NET cryptography APIs and enforce TLS for secure communications.
✓ Use static code analysis, dependency vulnerability scanning, and secure CI/CD practices.
Requirements● Basic understanding of C# and .NET - You don't need to be an expert, but you should be comfortable writing and running simple C# programs.
● Familiarity with Visual Studio or Visual Studio Code - We'll use these tools to build and test secure .NET 10 applications.
● Basic knowledge of web development - Knowing what APIs, HTTP requests, and databases are will help you follow along more easily.
DescriptionWelcome to Secure Code in C# & .NET, your comprehensive guide to building secure, compliant, and resilient software in the Microsoft .NET ecosystem. This course takes you far beyond theory-every module combines hands-on coding labs, real-world attack simulations, and AI-assisted security workflows using GitHub Copilot and modern .NET features.
Whether you're developing enterprise APIs, web apps, microservices, or cloud-hosted applications, this course will teach you how to think like an attacker and code like a security engineer.
What You'll Learn
1. Foundations of Secure Software Development
• Understand the Secure Software Development Lifecycle (SSDLC) and threat modeling in C#.
• Apply OWASP Top 10 principles directly to .NET codebases.
2. Secure Authentication and Authorization
• Implement secure login flows using .NET Identity, JWT tokens, OAuth 2.1, and OpenID Connect.
• Enforce multi-factor authentication (MFA) and role-based access control (RBAC).
• Prevent broken access control and privilege escalation using horizontal and vertical access policies.
3. Secret Management and Configuration Security
• Safely store and access application secrets
• Avoid secret leaks in GitHub and CI/CD pipelines.
• Automate configuration protection in local, staging, and production environments.
4. Data Security and Compliance
• Protect data at rest and in transit with AES encryption, TLS, and Transparent Data Encryption (TDE).
• Implement GDPR, CCPA, and HIPAA compliance practices.
• Prevent excessive data exposure and ensure logging without leaking PII.
5. User Input Validation & Injection Prevention
• Master validation and sanitization using Data Annotations, custom validation attributes, and schema validation.
• Block SQL injection, command injection, and XSS attacks.
• Implement allowlists, regular expressions, and secure deserialization patterns.
7. Secure Build and Deployment Pipelines
• Configure secure build processes with GitHub Actions, Azure DevOps, and Docker.
• Perform dependency checks, supply chain validation, and code signing.
• Apply the principle of least privilege in hosting environments and infrastructure.
8. Secure AI-Assisted Development with GitHub Copilot
• Configure Copilot for secure coding-block public code matches and filter unsafe suggestions.
• Use Copilot Chat and Agent Mode to find, fix, and prevent vulnerabilities.
• Integrate AI code reviews and Copilot Business features for enterprise-level assurance.
Technologies and Tools Covered
• .NET, C#, Identity
• Entity Framework Core, Azure Key Vault, GitHub Copilot
• JWT, OAuth2, OpenID Connect, MFA
• Security Code Scan, OWASP Dependency Check, DPAPI
• Visual Studio, GitHub Actions, Azure DevOps
Why Take This Course
Because secure code is no longer optional. From data breaches to AI-generated code vulnerabilities, modern developers must learn to integrate security, compliance, and automation into every line of C# they write. By the end of this course, you'll not only write secure, production-ready code, but you'll also know how to use AI tools like GitHub Copilot to prevent vulnerabilities before they ship.
Master the art of writing Secure Code in C# & .NET - powered by AI, protected by best practices, and built for the future.
Who this course is for■ .NET Developers (beginner to advanced) who want to learn how to write secure applications in C# and .NET, beyond just making their code "work."
■ ASP.NET Core Developers building APIs, Razor Pages, MVC, or Blazor applications who need to protect authentication, authorization, and sensitive data.
■ Software Engineers & Architects responsible for designing enterprise applications that must comply with security best practices, regulations (GDPR, HIPAA, PCI DSS), and OWASP guidelines.
■ DevOps & Cloud Engineers who manage deployments of .NET apps to Azure, AWS, or on-premises servers and need to secure build pipelines, configuration, and secrets.
■ Students and Career Changers learning .NET who want to strengthen their portfolio by demonstrating knowledge of secure coding practices-a critical skill for landing developer roles.
